Shanghai Expo Witnesses the World’s Largest Multitouch Display Wall

MultiTouch and Riolab have teamed up to develop the world’s largest high-definition (HD) display called The Wall of Chile. The multitouch display features a 4 m long and a 1.2 m high display wall, which allows viewers to watch thousands of photographs and HD video for over six hours. The HD display was launched at the 2010 Shanghai Expo.

The display wall features a Chile map as the 16.5 Megapixel main interface, and was programmed by utilizing the MultiTouch Cornerstone software that allows dynamic integration of applications. The unit was designed by Francisco Arevalo, Tommi Ilmonen and the team, and a number of authors and organizations also contributed to the wall.

MultiTouch’s computer vision device has been integrated with a software, which converts touch into programming languages. The company had demonstrated the first Windows 7 applications for its MultiTouch displays at the Consumer Electronics Show (CES) 2010. The Cornerstone software supports numerous development environments, programming languages and protocols such as Microsoft Visual Studio, Silverlight and Adobe Flash/Flex/Air, among others.

The modular display allows users to navigate the images by tracking the hands and fingers for enhanced interactive experience. In fact, it can track any number of hands on the screen at a rate of 120 frames per second in any environment. The display walls can be configured either as stand-alone or commercial systems. They have built-in multitouch and multiuse capabilities and offer high-definition 1920x1080 pixel resolution at each display.

MultiTouch’s Chief Executive Officer, Petri Martikainen, stated that the aim of the company is to provide a dynamically updated information that promotes enhanced interactive experience for consumers.
